Hi All,
I've not checked in for a loooong while but thought some people might like to see what I've been working on over the last couple of years since I dropped off the forums! (although obviously I still play KSP in my down time )
Go For Launch is a full simulation of project Mercury. It's not KSP, you don't build rockets etc, it's focus is on accurately recreating the Mercury spacecraft including fully interactive and functioning IVAs. It has support for VR although it can be played on a monitor too (all switches interact with the mouse).
It's on steam early access, so just google it if you are interested! EDIT - Some confusion as to what Early Access is, it's already available to buy on Steam, right here - http://store.steampowered.com/app/467400/Go_For_Launch_Mercury/
Here are some screenshots!
